Sporophila corvina
Drawn from open occurrence records in and around Tortuguero, aggregated onto a 25 km grid. A cell is matched by its centre, which can sit up to 16 km outside the boundary, so this covers the surrounding country too.
Occurrence records measure where people looked and found something, which is not the same as where the animal is. This is a relative likelihood, not a probability.
Records exist for January, February, March, April, May, June, July, August, September, October, November and December, with the widest coverage in January, May, July, August and October. A quiet month can mean the animal was absent, or that nobody was looking.
A grid cell is a square of the map, not a sighting: 7 squares of 25 km carry records for Variable Seedeater in and around Tortuguero, and the 6,070 records behind them were collected by other people and published openly. Nothing here counts animals, and a place with more records is not always a place with more animals.
Osa Peninsula, Tortuguero and Corcovado are among the six atlas places where the Variable Seedeater is recorded. Most records of the bird concentrate in Costa Rica, Panama and Ecuador. Across ten countries, the atlas holds about 294,000 records of this species, and the map follows where these records gather most thickly.
Of the 102 species with an atlas page recorded in and around Tortuguero, the Variable Seedeater is the 7th most recorded.
